Powertrain Control Module = under right side of dash, near blower motor.
Engine Control Module = same as above
Vehicle Control Module = same as above

All Suburban vehicles are equipped with only one of these choices. Good luck.

Cruse control on 2008 Chevy Suburban stopped working. Changed the brake lamp switch (twice). Any suggestions? Where is the fuse located?

This is a computer controlled system (BCM) supply's power to switch .Voltage is supplied to the cruise control switch via the steering wheel control switch reference voltage circuit supplied by the BCM.
The following are the main components of the Cruise Control System:
• The accelerator pedal
• The stop lamp switch
• The body control module (BCM)
• The cruise control switches
• The engine control module (ECM)
• The throttle actuator control (TAC) motor
• The vehicle speed sensor (VSS)

Taking your vehicle to a quailfied repair shop would be your best option . Using a factory scan tool to view input data from switches and sensors is the only way to diagnose the cruise control on your vehicle . Just replacing parts does not cut it .

The body control module (BCM) monitors the signal circuit of the cruise control switches. The BCM relays the cruise control switch status to the engine control module (ECM) via the GMLAN serial data circuit. The ECM uses the status of the cruise control switch to determine when to capture and maintain the vehicle speed. The ECM monitors the vehicle speed signal circuit in order to determine the desired vehicle speed. The ECM uses the throttle actuator control (TAC) motor in order to maintain the vehicle speed. For further information on the TAC System, refer to Throttle Actuator Control (TAC) System Description .

This is not a fuse problem !!!!!!!!!

You probably don't know what GMLAN serial data is ,do you ? It's GM 's version of C.A.N. How to Diagnose Controller Area Network CAN

Powertrain Control Module/EEPROM Replacement/Programming

Powertrain Control Module (PCM)
Notice: In order to prevent internal damage to the PCM, the ignition must be OFF when disconnecting or reconnecting the PCM connector.
Service of the PCM should normally consist of either replacement of the PCM, EEPROM re-programming or a KS module change.
If the diagnostic procedures call for the PCM to be replaced, the PCM should be checked first to see if it is the correct part. If it is, remove the KS module from the faulty PCM and install it in the new service PCM. The service PCM will not contain a KS module. DTC P0601 indicates the EEPROM programming has malfunctioned. When DTC P0601 is obtained, re-program the EEPROM. If a DTC P0325 is set, check the KS module for proper installation. If it is installed correctly and DTC P0325 is still displayed, replace the KS module.
The ignition should be OFF for at least 10 seconds before disconnecting power to the PCM so the IAC valve has time to move to the engine OFF position.

Speedo sensor faulty how difficult to replace

How do you know the VSS - vehicle speed sensor is bad ? The speedometer not working , have a DTC - diagnostic trouble code ? Most vehicles now ,from 1996 on , the VSS is an input to the PCM/ECM or TCM-engine control module . The vehicles have a network that modules talk on (serial data bus ) , The engine computer sends speed data to the instrument cluster ,where the microprocessor in the instrument cluster interprets an controls the stepper motor setting the speedo .
What year , make an model vehicle do you have ? GM vehicles had a problem with bad stepper motors !

    When the term Electronic Control Module (ECM) is used in this guide it will refer to the engine control computer regardless that it may be a Vehicle Control Module (VCM), Powertrain Control Module (PCM) or Engine Control Module (ECM).
    The Electronic Control Module (ECM) is required to maintain the exhaust emissions at acceptable levels. The module is a small, solid state computer which receives signals from many sources and sensors; it uses these data to make judgments about operating conditions and then control output signals to the fuel and emission systems to match the current requirements.
    Engines coupled to electronically controlled transmissions employ a Powertrain Control Module (PCM) or Vehicle Control Module (VCM) to oversee both engine and transmission operation. The integrated functions of engine and transmission control allow accurate gear selection and improved fuel economy.
    In the event of an ECM failure, the system will default to a pre-programmed set of values. These are compromise values which allow the engine to operate, although at a reduced efficiency. This is variously known as the default, limp-in or back-up mode. Driveability is almost always affected when the ECM enters this mode.


    See Figures 1 and 2

    0900c152800a7f97.jpg enlarge_icon.gifenlarge_tooltip.gif

    Fig. Fig. 2: ECM mounting scheme-1996 models
    The ECM is located in the passenger side footwell in the kick panel up to 1996. In 1996, the ECM is located in the engine compartment next to the battery.

    1. Disconnect the negative battery cable.
    2. Disengage the connectors from the ECM.
    3. Remove the spring retainer off and over the rail of the ECM on vehicles except 1996.
    4. Slide the ECM out of the bracket at an angle.
    5. Remove the ECM.

    To install:
    1. Install the ECM into the bracket.
    2. Install the spring retainer (except 1996) and plug in the electrical connectors.
    3. Connect the negative battery cable.

    Where is bank 1 sensor 2 located on a 1996 Chevy suburban ?

    'Sensor 2' means the sensor is downstream from the exhaust manifold instead of on the exhaust manifold.

    HO 2S
    The heated oxygen sensor is used by the powertrain control module to measure the amount of oxygen in the exhaust. The PCM uses this data to control the air fuel mixture in the engine. The PCM sends a bias voltage of approximately 450 mV to the oxygen sensor. At operating temperature the oxygen sensor signal varies between 0 and 1,000 mV. When the mixture is rich the oxygen content is low and the voltage signal will remain on the high side of the 450 mV mid-range. When the mixture is lean the oxygen content is high and the voltage signal will remain on the low side below the 450 mV mid-range.
    Typical oxygen sensor 93174g12.gif

    The oxygen sensors on later model vehicles are equipped with a heater circuit. The heater circuit in the oxygen sensor shortens the time required for the sensor to reach operating temperature and provides a more accurate signal.

    Put an injector noid light at the injector plug terminals to see if your getting a signal from the PCM(computer).If not try to find a computer from the same vehicle that works and swap it into yours to check.A PCM swap will take about 15minutes.

    Where is the PCM located on a 1991 Oldsmobile 98 Regency elite?

    The PCMor powertrain control module is only on 1996 and newer cars.Earlier models have a ECM or electronic control module/pcm.You want to change the ECM if its a 1992.Its located under the right hand side of the instrument panel.The ecm has a prom( programmable read only memory)in it.You will need to remove this from the old ecm and install in the new ecm.The ECM/PCM can be used in many different GM vehicles but the prom is very specific and must be used only in the vehicle it was designed.The prom will not come with the new ecm and must be carefully removed and installed on the new ecm.There also is a CALPAK in the ECM ( A devise for fuel delivery) This may come with the new ECM But make sure all parts are the same.You should get a vehicle repair manual to do this job correctly,and make sure you do not damage your PROM.Your PROM is very IMPORTANT!
